Gravity Railroad

After the planet suffered from a mild gravity calamity on a planetary scale, the great equator railroad ride got a bit more "interesting" to say the least. Commutors going from work from the southern hemisphere to the northern hemisphere are now in for quite a interesting ride, luckily the Interplanetary railway association invested quite a lot of credits in their railway systems so most of them remained intact after the, I must say, unremarkable state of events.
